The authors summarized the genetic theory of light carbon stable state by Mango. Based on large actual data, Mango found that the formation of light-hydrocarbon was controlled by a chemical process and the obvious invariance of relevant components of 4 C7 isomers that was the stable genetic model of light hydrocarbon. According to this model, Mango established the relationship between the light hydrocarbon parameter and the max-burial temperature; and discovered the difference of KI ,K2 parameters from distinct type of organic material. The authors analyzed the light hydrocarbon of lacustrine oils and marine hydrocarbon in northern Jiangsu Basin, and probed K1 ,K2 into use of determination of hydrocarbon originated from marine or lacustrine materials; and calculated the formation temperature of lacustrine oils and marine hydrocarbons. The results showed the formation temperature of lacustrine oils, which was in mature stage, was of fine correlation to sterane C2920S/（ S ＋ R）, and the formation temperature of marine hydrocarbons, which was in late mature stage, was higher than that for lacustrine oils.
